Given steady high pressure and mostly cloudy conditions in late April, fish the shallower bays and margins where spring temperatures are warming fastest—trout will cruise these areas between 8 and 11 a.m. as the cloud cover diffuses bright sunlight. If wind gusts exceed 12 mph during your session, switch from small dry flies or emergers to weighted nymphs fished on a floating line in 8–12 feet of water, where the wind chop masks your presentation. With air temperature at 11°C and the season shifting toward the peak of spring hatches, watch for sedge activity around weed beds and reed fringes; if you see rises or hatching insects, change to an olive or brown soft-hackle pattern fished with a dead-drift or gentle retrieve. Before the peak window closes at noon, move to slightly deeper water (12–16 feet) where cooler temperatures may concentrate fish during the brightest part of the day.
